“Your neighbour says her diamond ring was stolen and I’d like to ask you a few questions.” Sam told Jill.

“O.K.” agreed Jill

“Have you ever seen the ring before?” he questioned first.

“Oh yes, it’s very beautiful although it looks heavy and uncomfortable to wear.” was Jill’s reply.

“How much money do you think the ring is worth?” was Sam’s second question.

“Actually I’m not sure, Serina has never mentioned anything about the price.”

“O.K. Thanks, that’s all I need for now.” Sam said as he packed up.

Sam knows who stole the ring and why they did it. Do you know who it was, why they did it, and how Sam knew?

Solution
The thief was Greg. He stole the ring because he didn’t like his wife bragging so much. He thought that if he stole it then Serina wouldn’t have anything to brag about. Sam knew it was him because Greg cut in to try to frame Jill who obviously had no incentive to steal it.
